无线传感器网络正逐渐过渡到实际的应用,在这些应用环境中,WSNs会遭到曾经危害过因特网和无线网络的攻击。DDoS攻击是这类攻击中的一种。这一恶意攻击甚至可以导致一些大型的网络拒绝合法顾客,合伙人和用户的服务。本文通过使用一种简单有效的方法来检测DDoS攻击。与以前提出的基于统计知识的统计阈值方法不同的,该方法的动态阈值基于模糊数学,是一种鲁棒性较强的方法。 Wireless sensor networks are gradually transitioning to practical applications in which WSNs are attacked once they have harmed the Internet and wireless networks. DDoS attacks are one of such attacks. This malicious attack can even lead some large networks to deny the services of legitimate customers, partners and users. This article uses a simple and efficient way to detect DDoS attacks. Different from the previously proposed statistical threshold based on statistical knowledge, the dynamic threshold of this method is based on fuzzy mathematics, which is a robust method.
